A new PWM control method for AC to DC converters with high-frequency transformer isolation

The authors present a pulse-width modulation (PWM) control method for a switch mode rectifier on the basis of the idea of coordinate transformation. The proposed method realizes sinusoidal input current waveforms, a controllable input displacement factor, and an arbitrary output voltage waveform. This method is suitable for real-time control. Simulations and experiments carried out to confirm the feasibility of the proposed method are reported.<
